Stream Sediment Geochemistry for Mineral Exploration in Yukon's Aishihik Lake Area

985 stream sediment samples from the Aishihik Lake area in Yukon were analyzed for 53 elements. The samples were originally collected in 1985 from 934 sites and reanalyzed in 2014 using ultra-trace aqua-regia digestion ICP-MS. The work was conducted by the Geological Survey of Canada in conjunction with Yukon and federal departments.

Use Cases

• Identify mineral deposit signatures based on trace element concentrations in sediment
• Map regional geochemical anomalies for exploration targeting using the 53-element suite
• Compare historical (1985) and modern (2014) analytical results for the same sample splits
• Train predictive models for mineral potential using geospatial and geochemical features

Strengths

• 985 samples with modern ultra-trace analysis for 53 elements
• Includes original 1985 field data and 2014 reanalysis results for comparison
• Spatial coverage defined for the Aishihik Lake area (NTS 115H)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• 4 samples were not recovered due to a deficiency of available material
